Yeah. Peewee was his name. The Chihuahua. He was mad as a murder hornet and his rage and hate kept him alive past the lives of my grandmother's other two dogs. He also bit toddler me in the face once and I've never forgotten or forgiven that dog.
Wrong color... But that facial expression is a dead wringer for peewee. It's a shame I don't remember exactly what color his fur was. I think he was light brown??? I dunno. But that face is 100% accurate.
Chihuahuas and other small dogs are only aggressive because they are smol and in the wild they have to be aggressive to defend themselves from larger animals and predators.
